Haven't try this in real situation yet, but this set seems to work well.

Marshadow @ Lum Berry / Life Orb / Leftovers

252 Atk / 4 Def / 252 Speed

Jolly nature

- Bulk Up

- Spectral Thief

- Close Combat

- Shadow Sneak / Substitute

After using Marshadow for a while, status effects has proven to be problematic for it. So, using Lum Berry or Substitute can help with this. Bulk Up is not commonly seen. However, it improves matchup against defensive teams while also able to deal with offensive teams (Marshadow's strength). It has good sweeping capabilities with this set. Substitute can be used against predicted switch and status moves or to take weak attacks like Alomomola and Toxapex's Scald.

If using Shadow Sneak over Substitute, Lum Berry is highly recommended due to its vulnerability to status moves.
